Hello Greg, I agree with you that the article in SMT Magazine should be studied very carefully as it contains many errors in respect to SN100C. The testing performed was a DOE and was not an optimized run. There is also a statement on dross generatio

I take it you are talking about the older style IP feeders. If so, here is what you need to do..... Get yourself some mineral spirits,a tub you can submerse the parts in, and a couple nice paint brushes. 1.Dismantle the feeder and wash all of the

If your component meets ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires, then the problem is at your customer's operation. If the problem is at your customer's operation, it's very difficult to anal

I just went through the same problem. We have an inductor that is made with a bundle of 30-strands of Litz wire that is vaccuum coated with varnish, and have the ends of the wire bundles tinned that we have to solder to SMT pads on the board. The ind

Why don't you guys look at the "WORLD LEADERS IN SOLDER RECOVERY". EVS International make the EVS 3000 and EVS 6000 Solder Recovery Systems. Many other companies have tried to come up with different ways of recovering solder but the EVS is the best

Hi I use a lot of preforms for other specific applications. Personally I like indiums product but the lead time is awful and dont often deliver them on schedule. (im in the uk). Some manufactures make preforms out of solder wire that is pressed flat

I assume you talk about wave soldering. No-clean fluxes are widely used since 1987 or earlier and after all these years they have proven to be reliable. If you clean the board or not the dust bunnies etc. will still reach the board surface. If you us

Howdy aj, wow! Be prepared for serious problems with corrosion of your stainless steel workings of your pump. Last I looked changing a wave solder pot over to nitrated coating for electrovert was in the neighborhood of 18-20K. I'm not a betting man

Hi, The bath is titanium coated, and the machine is only 2 years old, and was designed for lead free, so we know we don't need to change anything. The reason the supplier gave for suggesting the bath change is "other companies are doing it" and it'

I have read some threads about poor wetting on palladium-silver (Pd-Ag) coated components. I followed the suggestions, but I am still having a problem. The part is an 0603 chip type (Vishay varistor). The Process: solder paste is lead-free Alpha Met
